{"version":"1.0","type":"rich","title":"Fork of Circles on a Map","description":"This visualization shows global population by country, with the area of each circle proportional to that country's 2018 population. It uses a natural Earth projection with D3’s `geoPath` for the map. Pan and zoom via the `zoom` control, and hover reveals detailed population figures. Data is loaded from a CSV of UN population figures and a TopoJSON world atlas, processed with `topojson.feature`. Circles are drawn using SVG, with a size legend generated by `sizeLegend` and a color legend using `colorLegend`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2914c21abc6248228ba0c4c5173495a8?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
